Not every stained glass window is in a religious building. This one is in the Château de Belcastel,
in the little town of Belcastel in Aveyron, France. The Château dates back originally to the 9th century,
and was abandoned in the 17th century, when it fell into ruin. It was restored in the 1970s with the help
of a dozen stonemasons and 10 stained-glass experts.
